This is very common for out of area owners. 

I made an urgent request to obtain a duplicate key to the common area (note that this key is required to be able to enter my condo unit), and the property manager has not delivered the keys 7 days later, in spite of letting him know this is urgent.

Consider this scenario.

Certain things can happen which revive the redemption period but not all that common in residential transactions.  

@Ashley WolfeI probably wouldn't use an agent for the off market properties unless they are sharp with common sense and can negotiate.

As for a trust, and ALL of these scenarios you should seek counsel from someone that knows the laws in your state, regarding real estate, taxes, etc.

If the seller agrees to pay them then I don't think asking for a discount is relevant.On the other hand if they weren't going to pay them then you would subtract some or all of them from the purchase price.You should strive for a win-win scenario, not to take advantage of the seller.

Think through various scenarios to ensure it is complete.
